2016/11/2 11:00:32

Stripper plate is commonly used in plastic mold ejector mechanism, the other  is ejector pin. Stripper plate push forward the parts rim when demolding, the  parts depart from the mold. When should we use stripper plate? It need consider  the parts structure and surface quality.

a) If the parts are thin wall product or need deep cavity, there need stripper  plate or stripper plate and ejector rob which can stably make parts demold.

b) When it requires no ejector rob traces on plastic parts surface, there need  stripper plate. It mainly includes clear parts, or the parts that appear after  the molding surface assembly.
